Question

please tell answer of this

Answer 1

Step-by-step explanation:

b(5-a) -a ( b-5)

5b- ab-ab+5a= 5a+5b-2ab

5(a+b) -a 2ab

Hence, b(5-a) -a ( b-5)

5(a+b) - 2ab .

Answer 2

Given,

Equation: a(b-5) and b(5-2)

To find,

The value of a and b

Solution,

Simplifying first equation= a(b-5)

= (a x b) - (a x 5)

= ab - 5a  / eq1

Simplifying second equation= b(5-a)

= (5 x b) - (b x a)

= 5b - ab  / eq2

According to question

Subtract eq1 from eq2

= ( 5b - ab ) - ( ab- 5a)

= 5b - ab - ab +5a

= 5a + 5b - 2ab

The answer to this question is ( 5a + 5b - 2ab)
